B07 – Guided Interpretation #7:
Formation Testers
This example gives an overview of the Formation Tester module. The objective of this session
is to learn how to load and process data from formation tests and the results of their
interpretation (i.e. discrete values of reservoir pressure, and mobility or permeability).

• Loading the data
.1.1 • Formation tests specific data types and mnemonics
Calling the ‘Formation testers’ option amounts to creating a specific object in the data
hierarchy, below the ‘Survey’ level. A ‘Formation Testers’ object comprises a number of
channels, for the reservoir pressure, mobility, and permeability. Specific data types in the
Emeraude database are:
Data Type
Default built-in mnemonic
Units
Formation pressure
RESP
Pa, kPa, psia, psig, atm,
bara, barg, kg/cm2, m
Formation mobility

md/Pa.sec, md/cp,
Darcy/Pa.sec, Darcy/cp,
m2/Pa.sec, m2/cp,
cm2/Pa.sec, cm2/cp,

Start Emeraude and create a new document, a new survey and load the data from the file
B07ft.las. This file contains the following curves: Wellbore Temperature and Pressure,
Reservoir Pressure, and Reservoir Mobility.
Remarks: Although formation tests data are acquired as stationary measurements, all depths
of interest should be loaded in one go, i.e. do not load the data as multiple discrete stations,
but as a versus depth information. You could load from distinct sources; for instance the
wellbore pressure vs. depth could be in one file, and the reservoir mobility (or permeability)
and reservoir pressure vs. depth in another one.
